ART 0F EXTRAGTING GOLD.

Specification of Letters Patent.

Patented Dec. 7, 1920.

Application filed May 27, 1918. Serial No. 236,908.

To all whom it may concern lie it known that 1, CHARLES A. PERRY,citizen of the United States, residing at Berkeley, in the county ofAlameda and State of California, have invented certain new and usefulImprovements in the Art of Extracting Gold, of which the following is aspecification.

This invention is an improvement in the art of extracting gold from finesand.

It is a well known fact that in gold producing districts, in placermining and on gold beaches, much free gold is lost in fine particles,which escape the usual processes for the recovery of gold. Any devicewhich will save these particles of gold bearing sand will result in amaterial gain in the recovery of the precious metal in new districts andmake it possible to profitably rework old diggings. The principal objectof the invention is to provide a method and means for the recovery offine black or gold bearing sands, which are lost under present iethods,or recovered with great difficulty and indifferent success byquicksilver or other expensive methods. another object is to provide adevice simple and inexpensive of manufacture, which will operate with aminimum amount of water pressure, making it available wherever placermining is possible. 5

These objects are accomplished by the novel structure described in thefollowing specification and illustrated in the accompanying drawings; inwhich,

Figure 1 is a vertical central section of my improved device. Fig. 2 isa perspective View of a detail.

Referring to the drawings, 1 indlcates a water pipe of usualconstruction, connected with any available source of water pressure. Thepipe 1 is threaded into one end of an elbow 2 into the opposite end ofwhich is projected an externally threaded discharge nipple 3. On thelower end of said nipple 3 is a locknut 4, to form a support for thebottom of a bucket 5, through a hole in which extends the nipple 3. Alocknut 6 working on the nipple 3 is then screwed downwardly until itrests against the inside of the bottom of the bucket. Thus the bucket isrigidly supported in position. On the upper end of the nipple 3 isattached a threaded supporting sleeve 7 to which are soldered orotherwise secured, the end of a suitable number of similar brace arms 8,four being shown, the opposite ends of which are bent outwardly anddownwardly and secured to the internal walls of a sheet metal separatorcone 9, closed at its apex and open at its base. The apex of the cone isin the center of the bucket 5, and is surrounded by the lower open endof an annular hopper 10, which has a rounded down turned edge 11, forengaging the top edge of the bucket 5.

In operation my process is as follows Sand suspected of containing freegold or gold bearing particles, is shoveled into the hopper 10 whilewater is flowing through the pipe, and in and out of the cone 9, andthrough the hopper 10, traversing the course shown by the series ofarrows. The action of the water under pressure and by reason of thisdevious course causes the dirt and light sand to be agitated anddissolved or carried away with the water while the gold, sulfites andblack sand settle to the bottom as indicated at 12, for future recovery.

Having thus explained the nature of the invention, and described anoperative manner of constructing and using the same, although withoutattempting to set forth all of the forms in which it may be made, or allof the forms of its use, what is claimed is 1. An improvement in the artof separating minerals comprising a water supply pipe having a dischargenipple, a receptacle into which said nipple projects, a separator conesupported by said nipple within said receptacle said cone inclosing thedischarge end of said nipple and being mounted concentric therewith.

2. An improvement in the art of separating minerals comprising a watersupply pipe having a discharge nipple, a receptacle into which saidnipple projects, a supporting sleeve detachably mounted on the dischargeend of said nipple, and a separator cone supported by said sleeve andhaving its base inclosing said nipple.

3. An improvement in the art of separating mineals comprising a watersupply pipe having a discharge nipple, a receptacle into which saidnipple projects, and a separator cone within said receptacle inclosingthe discharge end of said nipple and concentric therewith, and ahopper-like cover engaging the top of the receptacle and having anopening concentric with said cone.

4. An improvement in the art of separating minerals comprising a waterpipe having a discharge nipple, a receptacle concenagainst both sides ofthe bottom of said trically supported by said nipple, a separbucket, ahollow cone detachably mounted ator cone supported by said nippleconcenon the inner end of said nipple, and a cover trio with saidreceptacle and inclosing a detachably mounted on the top of said 5portion of the nipple, and a hopper supbucket and provided with anopening di- 15 ported by the receptacle and having an openrectly oversaid cone.
